Does anyone have a recommendation for a cleaning solution used in an ultrasonic cleaner for cleaning RMA solder paste off stencils and adhesive off pcb boards. I am going to be evaluating Armakleen 2001, Zestron Vigon SC 200, and Aqueous Technologies

Your selections are good, assuming you are talking about cleaning raw paste, rather than reflowed RMA. Maybe add Multicore Prozone, JNJ Aquasonic, and Kyzen Aquanox.

I�m using Zestron's Vigon sc 200 in our ultrasonic cleaner. It works great for cleaning our adhevises and pastes (RMA and no clean) from stencils and misprinted PCBs. We used to use a saponifier which did a terrible cleaning job and was a real pain t

As I mentioned in the previous string we are happy with Electrolube "SSS". The guy who built our ulrasonic cleaners recommended it and it works very well. You don't have to change tanks or machines for a switch from paste to adhesive. It doesn't leav

Can you tell me a little bit about the Zestron product. How many stencils do you clean and much Zestron do you use per month? What is the cost? Do you mix it with water? If so, what temperature? How do you get rid of the waste? Thanks. Kerry

You should check the archives, there has been much written on this subject in the past. Asking about the correct chemistry is wise. It never ceases to amaze me how many people think ultrasonics will work without the proper chemistry. Without the rig

5 stencils/day. Not sure of the cost, it is high, but I only use a little each month so it is cheaper than the 50+ gallons I was dumping out each month of the old stuff. Mix it with water and use at room temp (don�t have any eaters).Don�t create any

I know it is not what you want to hear, but first and foremost, you must consult your local regulating agencies and here is why: Solder paste contains heavy metals. We are all familiar with the problems associated with lead, but lead free solder pas

There is also an article in the March 2007 issue of U.S. Tech magazine that reviews ultrasonic cleaning technology for PCBs titled "Reducing the Cost of Misprinted PCBs". The information is also relevant to post reflowed PCBs. A PDF copy of the art

We are purchasing an ultrasonic cleaner to clean pcb asseblies that have been produced with water soluble flux based solder. After cleaning a batch of assemblies, the water in the cleaner will need to be disposed of. My question is: Do we need to
